REVERSIBLE VIINDQW.

' To all whom it may camera:

Be it known that 1, DAVID ADG R, a Subject of the Shah of Persia, and'a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Reversible Windows, of which the following is a specification.

This invention relates to thatclass of reversible windows in which the sashes are adapted to slide vertically and pivot-horizontally inathe window frame as the operator may require. I Y

The objects of .the present improvement are:

Toprovide a structural formation andassociation of parts whereby an effective and very substantial guiding connection between the window-frame and sashes is attained and with-which the weatheris excluded in an effective manner. v To provide 1n'connect1on with such guiding means, a simple and substantial pivotal means adapted for coacting operationtherewithyand with which a'safe and convenient pivotalmovement of the sashescan be ef-' fected, all as "will hereinafter more fully ,appear.

In the accompanying drawings Figure 1,1is a fragmentaryelevation with parts in section, illustrating the preferred Fig. 2, is aperspective view of one of the guide rails in a de'tached COIIClltlOn;

Fig, 3, 1s a similar V16W- of'the guiding Fig.-4, is a detail line 4e. 4. Fi 1.

c. Figs. 5 and6, are detail horizontal sections on line 5,-5, Fig. 1 illustrating the respective engaged and disengaged condition of the guide rails in the different operations of the sash." i i Fig. '7, is a detail sectional elevationon line 7,-7, Fig. 6. Q a Like reference numerals indicate like parts in the different views. 1

Referring to the drawings, 1 designates the window frame, which as in the present horizontal, section on type of reversible windows-is provided with vertical guide rgroovesQ, for the guidance of the upper and lower window: sashes'3,-'4, in place of the usual vertical guide strip and parting bead employed in connection with the-ordinary 'vertically moving window sashes. I

The respective sashes 3,.4 are formed with v Specification of Letters Patent.

full length of the vertical rails of the sashes s and which are adapted to register with the i uide grooveslQ, of the window frame.

, *ach recess 5 opens through a vertical-end wall of a sash rail and :is providedwith marginal opposed flanges 6, ,which in the present invention constitute stops and guides as hereinafter set forth.

g The -recesses 5 are preferably formed 'as large in cross section as. the strength and materialrequired 1n sa1d-vert1cal sash'rails will permit, and so thatthehereinafter described guide rails whichfit in said recesses may be of a corresponding size in cross section. I is f 7 designates one" fj't'he, vertical guide rails abovereferred to, arranged in an aforesaid vertical recess 5 of 'aflwindow' sash-and adapted to have, limited sliding movement 6 Each guide rail 7 is formed with vertical ribs orflanges 8 adapted for 'sliding contact with the opposed vertical walls of 'in said recess, as illustrated in Figs.v 5 and f a recess 5 and for a stop engagement with V theflanges-G of saidjrecess Ito limitthe inde endent outward movement ofthe' guide rail :in relation to thesash rail in which it is mounted.-

In the .normal, and -acti=ve position of the guide rail v7,il lustrated in Fig. 5 its outer portion has engagement, in *a'guide groove 2 of the window frame, to constitute in connection with a similar construction-rat the other end 'ofthe sash, the sole guiding" means between the" sash and frame in the ordinary vertical 'movement"-o-f said sash, 1 and constructed in the manner shown and described, provides a substantial, and effective guiding means, v.withf ample provision againstlateral movement'ywind leakage, etc.

c 9 designates a rack bar fixedly. secured to. a,verticalguide'bar 7 andadapted for op- I 7 by a manually rotatable 1 shaft 11 journaled erative'engagement with a pinion 10 carried in the window sash rail,and"adapted to impart movement-to said guide rail 7 into and out of its guide groove 2: of the ;win-,

dow frame, as may be required in attaining' a position of parts which .admitswof a pivotal operation of the window sash, or a return of said parts to. a position in which the window sash is confined toits normalj vertically sliding movement. -No claim-,to

no veltvto such'guide rail operating means,' 1s made and; any otherusual and ordinary 4 operating mechanism may be employed instead as the judgment of the constructor may direct. V

12 and 13 designate vertically separated and horizontally arranged guide stems, carried on a base plate 14 secured to a vertical sash rail with the said guide stems extending horizontally through the material of said sash rail and through the midwidth of an aforesaid vertical recess 5 of said rail, and so 7 that stems 12 and 13 may constitute horizontal guides forthe guide rail 7 aforesaid by means of guide orifices in said rail as shown. With such construction ready assemblage of parts can be achieved, as well as a subsequent disassemblage for the purpose of and lower guide stems 12 extend to a plane approximately even withthe end of the sash rail, so that in a pivotal movementof a win dow sash said stems 12 may clear the adjacent face of the window frame, while the central guide stem 13 extends beyond such end of the sash rail and into a guide groove conditions met with in a 2 of the window frame, with its free end portions preferably connected to the sash V cord 15 arranged in theusual manner and having the usual sash pulley and counter weight connections.

The aforesaid central guide stems 13 constitute the pivot means of a widow sash in a pivotalmovement of the same,'and with Y a view to afford pivot bases for said stems, the

window frame is formed with a plurality of horizontal orifices 16 which intersect the aforesaid guide grooves 52 of the window frame and are adapted to receive the removable bearing strips now to be'described.

'17 designates one of the bearing strips abovereferred to, adapted for insertion in the aforesaid orifice 16 of the window frame and preferably formed with an obliquely arranged bearing recess 18 inits upper edge adapted to receive and hold a central stem 13, when the sashis lowered to attain pivotal engagement of the parts. In the present improvement any required number of the orifices 16 maybe provided in vertically spaced relation, so'that the window sashes may have pivotal movements at different heights to meet the varied requirements and general use of the invention. I

As appliedto window structure the heretofore described arrangement of parts is duplicated at the opposite side of the window frame and sashes, and the described adjustments of the parts will be made in unison at both sides before effecting the different operations of the sashes above set forth.

Having thus fully described my said invention what I claim as new and desire to se cure by Letters Patent is 1.
